eg of unisexual flower - papaya, watermelon
there two types of pollination _ self pollnation and cross pollination
when tranfer of pollen takes places in same flower that is ,pollen from stamen of a flower reaches the ovary of same flower ,it is self pollination
when pollen of flower reaches the ovary of another flower ,it is cross pollination
the factors of tranfer are wind, insect etc
when the pollen land on a stigma (which is a sticky part ) it has to reach the ovary for that a tube grows out of the pollen grain and travelthrough the style (elogated part of flower) .
fertilization takes place where the zygote gets divided to form an embryo .the OVULE develope a tough coat and gets converted into a SEED the OVARY grows and ripe to form a FRUIT
